Kevin Durant faces a spell out of action after the Brooklyn Nets confirmed the extent of the knee injury he suffered in Saturday's win over the New Orleans Pelicans.

Coach Steve Nash was hopeful that Durant would avoid a layoff, but the news from his MRI scan was not what the Nets wanted to hear.

In a statement, the Nets said on Sunday: "Following an MRI this morning, Kevin Durant was diagnosed with a sprained medial collateral of the left knee.

"Durant is expected to return to full strength following a period of rehabilitation. Updates regarding his return will be provided as appropriate."

ESPN reported that Durant may be absent for the team for around four to six weeks.

The Nets' 120-105 win over the Pelicans improved their record this season to 27-15, but it came at the cost of losing Durant in the second quarter.

He had racked up 12 points in 12 minutes of action, before the injury occurred when Nets guard Bruce Brown fell backwards into the two-time NBA champion.

Durant is averaging 29.3 points per game this season, along with 7.4 total rebounds and 5.8 assists.

His absence will shift workload onto James Harden, with Kyrie Irving unable to play home games for the Nets due to his unvaccinated status conflicting with a New York City mandate affecting indoor arenas. Harden is averaging 22.7 points, 10.0 rebounds and 8.0 assists.

The Nets, who sit 0.5 games behind the Chicago Bulls at the top of the Eastern Conference, are next in action on Monday when they face the Cleveland Cavaliers.
